IMPROVEMENT IN FEED-MILLS.

S peciication forming part of Letters Patent No. 1526,883 dated May 2l, 187 2;

SPEGrEroA'rIoN.

To all whom it may concern:

I, GARDNER W. GIBsON, of Dryden, Tompkins county, New York, have invented an Improved Mill or Machine for Cutting Hay and Straw, with orwithout the addition of grain to the same, but with distinct reference to the cutting of the grain as well as hay or straw, of which the following is a specification:

My object is to make avpoWer-driven mill that will easily and rapidly cut and comminute hay, straw, cornstalks, or other articles of such nature, to a fine mealy state, and to use it Without, if I choose, but mainly with, the corn, oats, Wheat, or other grains, cutting and commingling and comminuting the grains or grain to a mealy state by the studs and knives of the machine, and not by the action of any millstone-grindin g, thus making a very finelypulveri'zed feed of the articles named, for general use and sale, by my mill. Of course it will need power and rapid speed to do this, and the use by hand will be somewhat less available. My invention consists mainly in the construction of stud-plates With adjustability to the cylinder, the entrance and exit of the machine, and the combined use of the various parts I shall name, so that the result shall be a cutting-mill.

Figure l is a view of my cutting-mill, the

. upper half of the boxing being removed. Fig.

2 is an end view. Figs. 3 are detached views of the changeable knives and stud-plates.

In Fig. 1, A is the stud-cylinder, moved by the belt-wheel B, having the flywheel C, two permanent sets of spirally-arranged studs, D and D,`sets of permanent studs D set parallel to the axis of the cylinder, and one or more'plates E E, changeable at pleasure, on which are set studs also parallel to the axis The knives F are fast to the boxing, and variable by the blocks G, and

l cut to any desirable degree. In Fig. 2, I is the entrance cap or hood, near the iiy-Wheel, and J the exit or discharge gate.

the cylinder. In Figs. 3, K is a side view of a removable stud-plate, the studs of which, are made square, flat, or other shapes, and are set so fitting the knives and cach set of studs as to secure the iineness of the cutting. 'Ihey are varied with each article cut as far as necessary. A belton the pulley B drives my cutting-mill.

The advantages and uses of my invention are apparent to those skilled in the art to which it appertains.

Claims. y
